Hello Tallenl, This property supports multiple users and groups. The documentation for this property describes the syntax, but that documentation is not yet live on hadoop.apache.org. Here is a copy of that documentation content from trunk:
<property> <name>dfs.cluster.administrators</name> <value></value> <description>ACL for the admins, this configuration is used to control who can access the default servlets in the namenode, etc. The value should be a comma separated list of users and groups. The user list comes first and is separated by a space followed by the group list, e.g. "user1,user2 group1,group2". Both users and groups are optional, so "user1", " group1", "", "user1 group1", "user1,user2 group1,group2" are all valid (note the leading space in " group1"). '*' grants access to all users and groups, e.g. '*', '* ' and ' *' are all valid. </description> </property> --Chris Nauroth From: Tallanel Siriel <tallanel.had...@gmail.com<mailto:tallanel.had...@gmail.com>> Date: Thursday, April 28, 2016 at 8:44 AM To: "user@hadoop.apache.org<mailto:user@hadoop.apache.org>" <user@hadoop.apache.org<mailto:user@hadoop.apache.org>> Subject: Multiples dfs.cluster.administrators Hello ! I send you this mail because I need to set multiple users with the same powers than hdfs in my hadoop cluster. Do you know if it is possible with the property dfs.cluster.administrators ? Do we put user or group in this property ? If I can put multiple items in this property, do you know what is the delimiter ? Best regards. Tallanel
